Abstract
The embodiment of the invention provides a compression-type circulating water cooling submersible electric pump. The compression-type circulating water cooling submersible electric pump is composed of a pump body, a guide vane, an impeller, a water inlet (upper end cover), a bearing, an electromotor rotor, an outgoing cable, an outlet box, an electromotor stator, a lower end cover and a circulating water cooling guide pipe. Negative pressure is used as a circulating water cooling power source in a compression circulating water cooling mode, the integrated guide vane with a guide pipe is used for balancing the downward pressure of a water outlet of the submersible pump and the upward pressure of water subjected to centrifugation of the impeller, the opening of the guide pipe of the guide vane is downward, part of water pumped in by the submersible pump enters the circulating water cooling guide pipe in the pump body through the inlet of the guide pipe on the guide vane and downward reaches the bottom of the submersible pump, the water spirally flows to the electromotor stator and the electromotor rotor at the position, with the bearing, of the bottom at the angle of 45 degrees, then, the water evenly passes through the gap between the electromotor rotor and the electromotor stator in an even encirclement mode, and finally the water flows out with pipelines evenly distributed at the net-separated lower end of the water inlet as outlets. Therefore, heat of the submersible pump can be fast dissipated, and problems caused by over-high temperature are avoided.
Description
Technical field
The present invention relates to a kind of Submerged Motor Pumps, saying more specifically a kind of pressure type recirculated water cooling Submerged Motor Pumps.
Background technique
Submerged Motor Pumps conventional in mine is because heat radiation is bad, all can there is the aging adhesion of stator winding in motor through use after a while, cause short circuit damage motor, these problems cause the applying unit of current submersible pump within the shorter cycle, submersible pump to be keeped in repair, to be changed, and have caused the huge waste of the resources such as human and material resources.
Summary of the invention
The embodiment of the present invention, for the deficiency of existing submersible pump, proposes a kind of pressure type recirculated water cooling Submerged Motor Pumps, comprising:
Described pressure type recirculated water cooling Submerged Motor Pumps is made up of the pump housing, stator, impeller, water intake, bearing, motor rotor, outlet cable, outlet box, motor stator, lower end cap and recirculated water cooling conduit;
Described recirculated water cooling conduit by integral type stator under shed as entrance, arrive described submersible pump bottom through pump housing inwall, with miter angle from bottom bearing screw to described motor stator and rotor place, again with uniform ring around the mode crack through described motor rotor and stator respectively, finally using described submersible pump water intake net every the equally distributed pipeline in lower end as outlet.
The advantage of the pressure type recirculated water cooling Submerged Motor Pumps that the embodiment of the present invention provides is:
Adopt water in territory to be drawn water as water-cooled source, without outer water filling source; Adopt submersible pump self negative pressure as recirculated water cooling power source, not only can alleviate the axial pressure that negative pressure causes stator, simultaneously without additionaling power source, reduce energy consumption, the more important thing is that negative pressure enough promotes current rapid flow, good water-cooling effect; The water outlet of recirculated water cooling is positioned at submersible pump water intake, and in the time that the plane of drawing water drops to water intake, the outside water filling of recirculated water cooling water outlet can improve the situation of water surface foreign matter obstruction water intake; In recirculated water cooling using process, without adding any mineral oils material, can effectively protect Water quality.
Brief description of the drawings
Fig. 1 is the structural drawing of a kind of pressure type recirculated water cooling Submerged Motor Pumps of providing of the embodiment of the present invention.
Embodiment
In the pressure type recirculated water cooling Submerged Motor Pumps providing in the embodiment of the present invention, the negative pressure that impeller centrifugal force is produced is for recirculated water cooling power source, utilize downward pressure and the centrifugal water of impeller of integrated strip conduit stator balance submersible pump water outlet to upward pressure, the conduit of stator is under shed, due to the effect of negative pressure, some can enter recirculated water cooling conduit in the pump housing by stator upper conduit entrance the water that submersible pump sucks, water-cooled conduit is through impeller, on pump housing inwall, dig the axial pipeline through submersible pump bottom downwards having, sentence on miter angle screw to motor stator and rotor place at bottom bearing, again with uniform ring around the mode crack through rotor and stator respectively, finally using water intake net every the equally distributed pipeline in lower end as outlet.So far reduce to after normal temperature by carrying out heat exchange with extraneous waters with the current of pump body heat, be inhaled into again submersible pump water inlet, realize submersible pump with this and dispel the heat rapidly, prevent because of problems such as part, wire that excess Temperature causes are aging, motor damages.
As shown in Figure 1, be the structural drawing of a kind of pressure type recirculated water cooling Submerged Motor Pumps of embodiment of the present invention proposition.Formed by the pump housing 6, stator, impeller, water intake (upper end cap) 1, bearing 3, motor rotor 5, outlet cable 2, outlet box 4, motor stator, lower end cap and recirculated water cooling conduit;
Wherein, described recirculated water cooling conduit by integral type stator under shed as entrance, arrive described submersible pump bottom through pump housing inwall, with miter angle from bottom bearing screw to described motor stator and rotor place, again with uniform ring around the mode crack through described motor rotor and stator respectively, finally using described submersible pump water intake net every the equally distributed pipeline in lower end as outlet.
Wherein, described Submerged Motor Pumps is made up of the pump housing and Water submersible electric motor, and electric pump adopts vertical, submersible motor under, the pump housing and water outlet be upper.
The adapted motor of described Submerged Motor Pumps is Submerged Motor Pumps motor, is water-filling wet type, and winding wire adopts copper core Fluroplast-4 6 insulated conductors.
Wherein, in aforesaid pressure type recirculated water cooling Submerged Motor Pumps, described recirculated water cooling catheter interior scribbles military vessel antifouling paint, on described pump housing inwall, digs and has axial pipeline, and as the pipeline of recirculated water cooling, in the pump housing, temperature rise is 6 DEG C-10 DEG C.In described outlet cable connector, adopt F4 raw meal belt, outer employing adhesive waterproof tape as insulation protection band.
In the time that submersible pump is normally worked, after the centrifugal force water suction of impeller High Rotation Speed, the conduit that the negative pressure that stator is produced forces a part of water to be drawn by the downward opening of integral type stator, enter along conduit the axial pipe of digging on pump housing wall and arrive motor bottom bearing, with bearing because of High Rotation Speed produce heat carry out after heat exchange, conduit on screw enters the ring duct being evenly distributed between motor stator and rotor, carry out arriving the recirculated water cooling water outlet that is positioned at submersible pump water intake below after heat exchange with the motor of High Rotation Speed, so far reduce to after normal temperature by carrying out heat exchange with extraneous waters with the current of pump body heat, be inhaled into again submersible pump water inlet, realize pressure type recirculated water cooling with this, submersible pump is dispelled the heat rapidly, prevent the part causing because of excess Temperature, wire is aging, the problems such as motor damage.
